above the earth. traveling about five miles per second. but slow down. nasa says there is absolutely no danger. >> it's not going to cause earthquakes, it's not going to cause any climate change. >> reporter: da14 was first discovered by amateur astronomers last february in spain. since then, nasa has been plotting its path and is certain there will be no impact. its closest approach expected to be near indonesia at 2:24 p.m. eastern on friday. images have already been captured on high-powered telescopes in australia. >> you won't be able to see it with the naked eye. with research and a decent telescope, you have a shot but your best bet may be to do what a lot of people around here will be doing, monitoring the nasa feed online. as it gets closer, nasa's powerful gold stone deep space communications complex will be taking radar imagery, research that could help scientists avoid disaster in the future. back in 1908, a smaller meteor hit in a remote region of siberia, destroying the landscape for hundreds of miles. and scientists blame the dinosaur's demise on a massive astroid. >> t
or totally unrelated. this is nasa and there's little ole earth and the asteroid you can see the distance away from us, courtesy of nasa. right now a mere 25,000 miles, six minutes ago before we went on the air, it was at 27,000 miles, going very fast. and so, that's how they have it calculated not going to hit us or graze us, but buzz us in about an hour and ten minutes right here. i hope we live. just kidding. they say it's not going to hit us. not totally true and, but they say there's no 'cause for concern, hello. you never know, do you? and in other news we're following another major story for you today as the president heads to the windy city, his hometown, to deliver what's been billed pass a purely economic address. but there's he a growing sense that the economy will not be the only topic of discussion. this 174 shootings and 44 murders, so far, reported in chicago. that's just by february 3rd alone, all right? so it's going to get worse and it was really bad last year. last year, the city saw 506 murders, and more than 2400 shootings. and what a mess! all this after this 15-year
. but on friday an asteroid is going to come really close to earth. but as carl azuz explains nasa says there's nothing to worry about. asteroid 2012 da14 is about half the size of a football field, and it's headed right for us, or right near us, but before you start worrying about this. >> it's a meteor shower. >> reporter: know that nasa says this: >> the close approach of this object 2012 da14 on february 15th in nothing to worry about. its orbit is very well known, we know exactly where it's going to go, and it cannot heat the earth. >> reporter: with concerns about the end of the world put to rest, lets check out some science on this bad boy. first of, the asteroid is cruising along its 17,455 miles per hour. that's fast. but not as fast as rockets have to go in order to escape earth gravity and get in the space. speaking of gravity, it's going to give the asteroid a little extra pull as it passes by. so, as this thing is closer to earth, it's actually going to get faster. just how close is da14 going to get when it passes by on february 15th? more than 17,000 miles away from the planet.
, congress directed the federal agencies including the faa and nasa collaborating in accelerating the integration of uas into the national air space. the faa modernization and reform act of 2012 contains provisions designed to promote and facilitate the use of civilian unmanned aircraft. we, on the subcommittee, know that you've been working hard and have made progress towards meeting the prescribed objectives, but we also know that there are many unresolved issues, both technologically and regulatorily. again, i go to the goal today to have the research to overcome technology issues and mitigate risk involved with uas integration into the national air space system. we're particularly interested in hearing about any advances towards eliminating as a as a vulnerabilities. the agreements on technological standards and the "washington post" reported nine american uas crashes occurred near civilian airports overseas as a result of pilot ere -- error. there's poor coordination with air traffic controllers. in august 2010, the "new york times" reported that a navy uas violated air space
? deflected in tehran or something like that? >> andrea: doesn't it make you nervous that nasa is being dismantled by the administration? how are we supposed to know when they are coming? >> bob: nasa was not who intercepted this. it was department of defense. it was not nasa. >> andrea: right. nasa doesn't have anything to do with space. >> bob: i don't think the republicans. this is a waste of time. if it hits your house, well -- this is not hateful. i don't want it to hit your house. if it hits the russians, too bad, too. any human being, too bad. with the exception of a few i can think of. >> eric: this is irrelevant. [ overtalk ] bronc you upset about that? >> eric: no. everything is fine. can we point out the weekend away that the department of homeland security spent the money on, they spent money on $40 billion in various projects like in arizona $90,000 to fund and install video monitoring system for security cameras in chicago. guess what happened? never put security camera up? >> andrea: what is going on? >> dana: this is strange. i understand a training video for a lot of th
and a meteorite. thank you. will? >>> a great deal of questions and mystery surrounding this. nasa ambassador greg red fern also the sky guy is here. always good to see you. >> you too will. >> whether or not this thing actually hit the ground? do we know that yet? >> i think that there was an impact because before we went on air i was surfing the net and they show a picture of a 26- foot wide crater in the ice. and in studying the video that we saw today. it looks like after the terminal burst which was a big flash that everybody saw was brighter than the sun. there were other meteorites that fell to ground that an expedition will go out and map the field where all this things landed and give us a good picture of what happened that day. >> the folks that actually do this. you call them hunters right? >> yes i can guarantee you there are people who have got their passports and they're on their way to there right now to join the people there. >> not just because they're interested. there's value here right? >> absolutely. i tell you with an event like this, you're talking tens of thousands of dolla

if the weather holds later today. nasa will launch first observing satellite into orbit. coming up a nasa scientist will join us live. good morning i'm tony perkins. >> and i'm allison seymour. happy you are with us on this monday morning. we know it's a little wet out there. tucker barnes is here to tell you when it's going to dry up. >> and most of the rain is out of here. not going to be a beautiful looking day. >> might get sun later. >> maybe a little sun. a few weaks of sun. today is not promising but tomorrow is. >> isn't that always the way, tuck? >> the sun will come out. rain showers to the east. we're generally done with the rain. not going to be a great looking day. the clouds are going to hold tough. a peak or two or sunshine. temperatures going to warm well into the 50s. should be even a little milder than what we had around here this weekend. temperature at reagan national 39. 39 dulles. bwi marhsall 38. these temperatures should jump 15 degrees or so by the afternoon. a little sun developing early afternoon. highs in the mid 50s around here. may do a 60 or so to our south.
into space. the land sat data continuity mission will blast off from california. nasa calls it the most advanced and capable spacecraft of its kind ever built helping to monitor environmental change and natural resources. it's about the size of an suv and will likely be in orbit for many years. once it's in space, the u.s. geological survey will take over operations. >>> take a look at these photos. nasa says a solar flare happened over the weekend. it sent particles in the earth's direction. that likely isn't enough to pose a threat. they call the eruption minor but long in duration. nasa says the biggest effect here will likely be auroras near the north and south pole. >> the auroras are beautiful to see. we benefit in that way for sure. >> for sure. >>>let check had with tom kierein for a look at all the rain coming down. tom? >> yes, we've had a tenth to quarter of an inch of rain late last night. raining lightly in washington right now. we can see the jefferson memorial from the hd city camera. we've had a lot of the rain tapering off across northern virginia, the district into mar
. nasa reporting it appeared brighter than the sun. traveling at around 40,000 miles an hour, fast enough that if you were to hitch a ride, it would get from you new york to l.a. in four minutes time flat. early estimates were it weighed ten tons. nasa says now more like 7,000. it ripped through the air like a blade through fabric triggering sonic booms and an immense shock wave when it exploded. when it shattered miles above the earth, we're told it released 20 times the energy, more powerful than the hiroshimo bomb in japan. it was powerful enough to knock down doors and shatter windows across one city. officials say more than 1,000 people went for medical treatment. flying glass blamed for most of those injuries. one witness saying when older women in the neighborhood spotted it, they started screaming that the world was ending. and just about everybody seemed a little freaked out. >> it was very confusing because the building was shaking a little bit, so initially i thought it was an earthquake. but then i knew i heard this loud bang, so i thought some sort of explosion, either a gas
-- these are not just a few disgruntled protesters. the lead nasa global warming scientist has announced it's game over for the climate if we approve the keystone pipe will be. gabe was arrested protesting the pipeline. he is nasa's lead scientist endorsed a book calling the world for ridding itself of industrialization by turning off the greenhouse gas machine. this man i interviewed about ecoterror and the pipeline, his inspiration to stop the pipeline. so, the leaders at nasa -- i call them nasa's resident ex-con -- is inspiring these people to point acts of ecoer toism, and they're against all forms of energy, which doesn't make send. if we're getting oil from democracy in canada, that's caught ethical oil, as opposed to getting from nye jeer -- nye nigeria or the middle east. the. >> neil: what is scary, the ends justify the means and if push came to shove and it meant tearing the thing down or doing god know's what, without this oil, it's a better world for us? that is crazy. >> yes, it's not about not in my backyard so much as they're worried about the extra co2 that would be emited in the atmo
apparently unfounded. nasa is using radar and other technology to study how the asteroid behaves, including its rotation rate, its composition and how it's impacted by the earth's gravity. the idea is to learn enough to prevent cat as it sfroe fee from it threatening in the future. >> we're going to get a lot of information about the asteroid. we're interested in its future motion, whether or not it could come back, whether it threatens the earth. >> reporter: the odds are either this one or another will be back. an asteroid impact the earth about every 120 years on average. it will be visible in the rthernemisphere this evening if you have access to a telescope. for now it's on its way away from the earth out into outer space harmlessly rotating -- or resolving -- excuse me. harmlessly rotating -- i can't even think of the right word. orbiting the sun. harmlessly at least for now, jim. >> casey, thanks very much. we appreciate it. ? or gal lat particular news, a meteor lit up the skies over eastern russia. the blinding light was followed by a series of deafening explosions. listen to this.
of flying glass and debris. tonight we have learned there was no warning. more on that from nasa in a moment. we begin with kirit radia in moscow. >> reporter: it came out of nowhere. a bright speck in the sky, soon streaking across the horizon, followed by an almost apocalyptic scene. a blinding flash of light, and then all hell broke loose. [ explosion ] dizzying explosions, shattering windows, knocking these office workers to the ground. these students were lucky, protected by curtains from the flying glass. and these men barely escaped the blast. [ explosion ] in the streets -- pandemonium. terrified residents thought the world was ending. people started to panic. somebody screamed, the end of the earth, he says. the chaos of the meteor captured on cell phones and the dashboard cameras of cars, so popular here in russia. the blast was so powerful, it knocked down a wall at this factory. in all, over 1,200 people were injured, mostly from broken glass. 3,000 buildings damaged, over a million square feet of glass shattered. many were injured after going to the window to check out the flash
, nasa has been charged by congress with keeping a 24-hour-a-day seven-day-a-week watch on the skies, and they're doing this principally with three observatories in new mexico, california and puerto rico, that have discovered about 98% of all the asteroid we know that are out there. >> axelrod: if they identify a potential threat what can then be done by way of a defense system? well, that's a real possibility. you don't want to destroy these things. they're too dangerous and it's too impractical. what you can do is deflect them. nasa has already perfected the art of landing on asteroids orbiting asteroids and we even fired an impactor into the side of a comet to study the debris. you can do the same impact mod welan asteroid and speed it up or slow it down by as little as a few centimeters a second. that way had it arrives at earth's orbit we've already passed by or haven't arrived at the rendezvous yet. >> axelrod: just a fraction. >> just a fraction. >> axelrod: in south africa today the extended family of olympic runner oscar pistorius came to his defense claiming the state's own
. bill: according to nasa, 100 tons of meet toors of gravel and dust hit the atmosphere and the earth every single day. the smaller strikes what we saw in russia happen ten times a year. that's new. scientists believe a strike by a meteor six miles across may have been responsible for extinction of the dinosaurs 66 million years ago. in case you're wondering on a friday have something to do over the weekend you mentioned the asteroid talking about past several days. they say there is no connection between that and this meteor. we'll talk to scientists throughout the morning. heather: a lot of experts. bill: meantime, six minutes past, the nightmare is finally over. what a slow crawl this was. thousands of passengers cheering the end of a cruise ship horror scene. touching land and kissing it like the pope. the carnival cruise triumph docking last night in mobile after putting what passengers through what they call disgusting conditions. now they say they are just happy to be home. who can blame them. >> i feel great to be off the ship and just being on land and, i get to see my family
there are a million such objects out there. nasa is doing a very good job cataloging all the ones they can, but so far they've been able to find just about 10,000 of them. so we're a little ways away from having the complete inventory. >> schieffer: well, let me just ask you this question-- is there something the government ought to be doing or science ought to be doing that it's not doing? >> actually, believe it or not we are handling this one well. in 1995, nasa authorized-- or rather, congress authorized nasa to scan the skies 24 hours a at day, seven days a week, to look for these objects and we're doing it at three observatories in california, new mexico, and puerto rico. and those three observatories have accounted for about 98% of the bodies we know are out there. now, there are ways to defend ourselves once we know it's out there. and we have the technology to do it. it's just a question of putting the money together and deciding to do that. >> schieffer: all right well, that is a little bit reassuring, and thank you very much for helping us on something that most of us know absolutely nothin
this afternoon around 2:25 eastern. nasa didn't know about the astroid until a year ago when an amateur astronomer just happened to spot it in our skies. but it seems a remote part of russia did get a visitor from space. at least one meteorite streaked across the sky this morning triggering powerful shockwaves. witnesses say the noise set off car alarms and broke windows and damaged a factory. at least 250 people were hurt, mostly cuts from broken glass. thousands of russian troops were put on alert. >> apparently according to the latest information we have, 20,000 first responders are being sent to the scene, three aircraft surveying the damage from the scene. again, all those folks injured from the broken glass of all the stuff that shattered during the collision. >> and it's cold there, so the people with shattered windows are in the freezing cold. so a lot going on. >>> now let's check our weather. mountain snow in the central rockies. showers from tennessee to southern illinois. heavy rain from orlando southward. snow around the great lakes and northern new england. >>> mostly 50s
. joining us now to talk all about this is our sky guy greg redfern, nasa ambassador. so we booked you to come in -- >> little did we know. >> you guys are good, top of the news. >> real good, man. how's the stock market going to do? >> we'll see. i thought the mayanna calendar was -- >> child's play. >> all right, greg, let's talk about this event. most people are just hearing about it. >> boy. >> a meteor, how big do we think it was? >> well, the latest news report said that this was probably about 10 tons and i'm thinking it's probably the size of a big suv, came in the atmosphere, they were figuring about 33,000 miles an hour and it exploded at about 18 to 20 miles or so above the earth's atmosphere. this is incredible video, incredible. so you're seeing the fireball, ball like coming in. >> it's essentially melting as it's coming into the atmosphere? >> it's blading, it's coming in, it's leaving all of this material, the earth's atmosphere, it's causing friction, it's making its surface a blade away, it's building up this shock wave in front of it and the fireball can't withstand
,200 miles of earth's surface but then cruise safely back into space. >> reporter: nasa says it is the largest to fly this close to earth since the agency started keeping track. while the experts say it won't hit the earth, 130,000 metric tons of flying mass still makes people a little nervous. >> an impact by an object the size that will pass next week happens about every 1,200 years. >> reporter: to understand the true impact of asteroids striking earth, you have to travel back 66 million years. that's the time frame researchers at uc berkeley have newly pinpointed as the demise of the dinosaurs. >> the dinosaurs we think are wiped out around 66.043 million years ago. that's to within about 320,000 years. >> reporter: in a paper published this week, the group noted along with volcanos, the final nail in the dinosaur coffin likely fell from space. >> one is that an asteroid slammed into the earth. that wiped out the dinosaurs and a lot of life on earth. >> reporter: next friday's asteroid path isn't expected to be quite as spectacular but oakland space center will offer the
that was gunned down. and tim cook, and a nasa employee known as mohawk guy, there he is. he gained the nickname with the launch of the mars rover, curiosity. you can watch the state of the union dress tomorrow at 5:45. >> the governor of texas is making big claims, he said that the conservative state has knocked california off the perch as the nation's business leader. governor rick perry made the comments to the mercury news, this week he has meetings in san francisco, silicone valley and los angeles. he is trying to lure businesses to the sunshine state by show casing their best qualities. in the interview of course perry reportedly took shots at governor jerry brown and said, austin is posed to be the next silicone valley. and jerry brown said it was a cheap gimmick. >> a man is suing the coast guard for his pilots license. he is blamed for causing the worst oil spill in the san francisco bay in the decade when he crashed into the bay bridge. he was at fault and his pilot's license was in the process of being revoked. instead, he retired. his credentials were valid to 2010. the coast guard r
of collisions. >> reporter: aware, but how well is the world prepared? nasa budgeted $20 million last year to look for objects that may hit the earth but some scientists say more money should be spent on detection and ways to avoid a possible collision. >> we've gotten very good at finding the big things, the kilometer sized objects. we're working down to smaller objects. but there's many more of the small objects like these than there are of the big ones. >> i'd say the appropriate technology for deflecting a dangerous asteroid could possibly be a nuclear bomb, but the key is catching and detecting the objects early. >> reporter: experts say that friday's blast could have killed thousands of people had the meteor landed in the middle of a large city, a reminder they say that even smaller objects threatening earth should be a wake-up call. >> we knew factually we lived in a celestial falling rock zone, but friday taught us, reminded us that we live in a shooting gallery, in fact, we got into a crossfire. >> reporter: the power of the universe on display here on earth. michelle franzen, nbc
in plastic with that dress. >> be nice. >> keep it clean. >>> the space shuttle may be history but nasa is keeping busy. how the latest launch today could help us keep better tabs on the planet. >>> at 5:20, the encouraging developments in the fight against teenage pregnancy. >> putting the power of your iphone into a device you can wear on your wrist. >>> the perfect bouquet for your >>> valentine's day is a few days away. florists across the country are gearing up for one of the busiest days of the year. new advice for lovers who want valentine's day to be perfect. tip one, do not wait. place your orders to make sure your special someone gets his or her flowers on time. buying local is the best way to ensure that your flowers aren't dead and wilted by the 14th. before you buy, of course, watch news 4 at 5:00 tonight. because liz crenshaw will show you that not all roses are created equal. my favorite are peonies in case you need to know, aaron. >> dual noted. gas prices continue their rise towards $4. the national average $3.58. seven cents more than a week ago. d.c. drivers paying $3
. there is no risk, but it is a warning of what is out there. nasa attract the asteroid. they said there was no danger. an observer pick out the tiny white shape of the rock going through space. >> we have always focused people's minds on this. we have known for a while that there are things out there. this is just a very timely reminder, a reminder of why it is important for us to keep scanning the skies. >> all of this is a wake-up call. the asteroid that was much larger did pass us by. when it comes to protecting ourselves, there is not much we can do. bbc news. >> for more on today's events, i spoke to a chemist at the smithsonian in washington. what is going on out there? first of all, you have this need your read, and then you have this asteroid. >> absolutely, a very busy day. i think it is unprecedented. a really truly interesting day, to have them passing so close that it is actually visible, and then to have this media right in russia. it is a special day. >> what is causing it? we did not know any of this was coming? >> no, we were actually caught a bit by surprise. we h
-meter asteroid and nasa says it will get closer at around 7:30 gmt, pm, on friday. it is not expected to hit the earth but the bad news is it could affect satellites orbiting the earth. >> satellites of this size passed by the earth once every 40 years in the last someone hit the earth was in 1908 and caused devastation in a region of russia. the next time could be 40 years, an impact could damage the world's communications system badly. the world relies on the satellite systems far more heavily than most of us realize. all of our aircraft and motor transport systems run on satellite gps and mills and many of the world's clocks are based on signals from space and most of our telecommunications and television signals, at some point, pass across satellites. if the satellite system was damaged, the world would go dark, on that cheery little mouth, --note, it will affect telecommunications. >> thank you very much, not very -- nothing very dark about you. still to come -- could liverpool fc face racial abuse when they play in russia tonight? ♪ ♪ >> at least four people have been killed
to a nasa press conference where they are discussing the implications of all of this. >> that was horrifying. >> joe, welcome to the show. >> thank you, andy. >> the head of the near earth object program says he thinks this was an event caused by the atmospheric impact, but you disagree? >> yes, i understood some of those words. i think this is proof about the weakening of meteors and asteroids. one of these things called kill all of the dinasaurs. my research and hard work has proven this for years. they call me crazy, but who is laughing now, andy? >> nobody here. is it. >> it is not funny. >> why do you think -- is it president obama? >> i'll tell what you it is. when bruce willis has to crawl in it to implode it from the inside, little pieces hit the earth. that's what happens. where was morgan free map? >> you you confusing movie world. nasa says this event is not related to the asteroid which flew by earth on friday. but isn't that exactly what they would say if the two things were related? >> exactly they don't want people to freak out. that's why they have been trying to send out ima
't happen, nasa assures us, is this asteroid and, oh, yes, it has a name, called da 14, they say it will not hit earth. still, you cannot ignore the buzz around this out of this world event. so we have this whole team of reporters for you and analysts to bring you this historic moment. we have a so-called asteroid hunter, former astronaut, coming on live this hour and next to talk about really what will be a historic moment as 2012 da-14 brushes by us earthlings. that will start just about ten minutes from now. right now, i want to go straight to casey wian, live in pasadena, california, nasa's jet propulsion laboratory. and i imagine the excitement is palpable. they're tracking the asteroid. tell me where it is now. >> reporter: well, it is over australia, brooke. they are very excited here at jpl. it is a very, very big day. they have been tracking this asteroid for nearly a year. today is the day it is going to get closest it is going to come to the earth as you mentioned, 17,200 miles. and right now, it is coming from the southern hemisphere, approaching the earth, basically

them. so nasa is very good the at finding the much larger ones. but these smaller ones we as humans have not put a lot of effort into it. at the planetary society, we have people that are interested in it and we found this one. >> i want to bring in jason carroll, at the new york museum of natural history. tell us what you're learn building this huge astroid that will get very close to us today. >> well, let me give you some perspective. this meteorite is just about roughly the size of a car, i would say. da-14 which will be swinging by the earth later on this afternoon is about half the size of a football field. so much, much, much larger. and it will be traveling at a rate of about 17,450 miles per hour. that's something like 4.8 miles per second. so it's traveling at an incredible rate. weighs much larger than the meteorite you see behind me here. it will pass by at it closest point about 2:24 p.m. eastern standard time. if you're in indonesia, that is your best vantage point to see. it will be dark there at that particular time. but if you have a telescope, you should be able to
, it was the sonic boom that caused the damage. now, that's the only old of this world story today. nasa says an asteroids half the size of a football field will miss earth today by 17,000 miles, that actually is very, very close. it's the closest known fly by for a rock of that size. it will pass inside orbitting satellites. don't worry it will not hit the earth. we are relybly informed. democrats continue to push, tax the rich. the latest pitch in 54 billion dollars brand new taxes on the rich and national review columnist joins me next and back on the opening bell which will be interesting this morning, in just a moment. my new hearing aids instantly changed my life - i feel so much younger. my husband has his confidence back. and he can enjoy the laughter of our grandkids again. i can have fun with my friends again. feeling isolated? ready to reconnect? the aarp hearing care program provided by hearusa can help. call hearusa at ... for a free hearing check-up. plus, receive a free $50 dining card when you get your free hearing check up. aarp members receive a 20% discount on breakthrough
with our telescopes. thanks to australia and nasa we can see imagery coming in from the eastern hemisphere. astronomers worldwide are watching, excited but not too worried. >> this asteroid is half a football field long but roughly the size of a 12 story building like this. and that is big enough to wipe out a city. but scientists say that is not going to happen. the real threat here though, is to communication satellites like the ones we use at fox news. the geosynchronous at 22,000 miles around the earth. at 1:24 eastern this asteroid penetrated the plane. there is no report of a satellite hit. it must exit the plane at 2:24 eastern. but scientists do not expect any collisions to happen. this is not only one out there. they are flying near earth's orbit. astronomers and telescopes around the planet are always looking up. >> we've seen and tracked about 9,000 of them right now. and about a thousand of them are potentially hazardous. so we look at those carefully. it turns out we're safe from those for many hundreds of years. >> the 1908 event in russia which leveled, wiped out forests for
close to earth, at least in space terms. as this nasa animation shows, the asteroid was just over 17,000 miles away from earth, traveling at about eight miles per second, actually inside a ring of television and weather satellites that surround the planet. named da-14, the asteroid was half the size of a football field. it passed, we can happily report, without incident. here to tell us about both events is astrophysicist and author neil degrasse tyson, director of the hayden planetarium in new york city. let's start with what happened in russia. how unusual was that in terms of size and impact? >> well, we couldn't know precisely how common that would be. all we can do is sort of look back at other sort of reported such events. for example, there was an air blast that happened in the airspace over india and pakistan back in 1990s. which happened to occur while they were in intense conversations about their nuclear buildup of arm ament. and so such a blast mimics greatly what would happened with the nuclear blast. it is an instant deposit of energy in the atmosphere. and so forth nat
